Kakuro Haven

About the Game

Kakuro is the number crossword: fill every run of white squares so it adds up to its clue, and never repeat a digit inside a run. Pure logic, no guessing, no timer breathing down your neck.

2,000+ puzzles, all free Six board sizes, from a gentle 2x2 Mini to the 30x30 Colossal. Nothing is locked, there are no packs to buy, and there is no limit on how many you can solve in a day.

A new puzzle every morning The daily is the same puzzle for everyone on the same date, with no account and no connection required. The dailies are their own puzzles and appear in no other tier, so finishing the whole library still leaves one waiting tomorrow.

No ads while you solve. Ever. Not a banner, not an interstitial, not a "watch this to continue." Ads keep the puzzles free and appear only between puzzles and on the menus.

Write in your own hand, on tablets Write digits straight into the cells with a stylus or a finger. The app learns your handwriting entirely on your device: nothing uploaded, nothing downloaded.
